Be it known that l," M G. Fmmrson, States, residing at in the pounty ot-C-ook and State of lllinoisg have invented certain new and useful Improvements in Floor-Strip Holders, t which the follow' gis a specification. i This invention relates in general to-build in constructions and his" more particular re erence to the floorsupporting construcln theconstruction of both concrete and wooden buildings, it is customary to provide a ough floor over which the finishing door The finishing ooris carried by and nailed to strips supported above the rough floor, usually on wooden blocks so that the water, gas and other pipes may be run inany direct-ion above the rough door and beneath the nailing strips. ln lieu of wooden blocks for supporting the nailing are sometimesemployed strips, metal chairs which perform the same blocks. I

The rough door, however, is not leveled with an degree of accuracy when laid and it there ore becomes necessary to accurately levelthe nailing strips upon which the fin-' This is most frequently blocks or metal chairsfunct-ion as the done by lifting the above the surface of the rough door and filling in beneath these blocks ortchairs subsequently sags,

with plaster or concrete so that the\ u per laces of the nailing strips arentthe requisite level. It frequently happens however, that before the plaster or concrete has-hardened, snmeone will step on the nailing strips or some weight will be imposed thereon which will depressthe supporting blocks or chairs into the plaster or concrete with the result that some of them will be disposed below the requisite level and with the result that when the finishing door is laid, it will not be perfectlylevel or it level when laid, it is insuficiently supported at some places and and in any event is very creaky.

Une oi the primary objects'oi my present,

invention is to provide a door strip holder or support on which the "floor strips are carried, each holderbeing vertically adjustable so that the door strips can be accurately I leveled irrespective of irregularities. in the rough floor and without employing filling material such as concrete or cement which, when used, is apt to become displaced before Specification of Letters Patent.

that accurate leveling of the floor strips is disturbed.

Anotl1er object of my invention is to proyide floonstrip holders which will be simple .1n constructlon, cheap to manufacture, and

' which can be quickly and easily put in place and adjusted as required, tobring the floor strips to the desired level. i

tages of my invention will readily appreciated as the same becomes better understood byreference to the vfollowing description' when considered in connection with the accompanying drawings.

Referring to the drawings, Figure l is a fragmentary structure embodying myinvention.

Fig. 2 1s a perspective sectional view perspective new of a floor showing one of my improved floor strip holders in position.

Fig. '3 is a similar view showing the holder adjusted to another position, and

lF-ig. d is a plan view of one or the holders with a door strip in position thereon.

' Referring now to the drawings in detail, the construction shown comprises a lower or rough door 5, which may be of any preferred construction, the form selected for the pur poses of illustration, being constructed of building tile and concrete, although my v invention is equally capable of use in connection with wooden rough doors or other types. The finishing door 6 is carried upon and nailed to a series of transversely extending nailing strips 4, and my invention is concerned primarily with the supporting of shown to facilitate bonding of the holding cement in which they are embedded, but manifestly the Webs might be provided with slots, apertures, or. other provisions for accomplishing thisresult, and as a matter of fact, when the devlces are to be used in wooden constructions, nail receiving aperfeet preferably, are, a

Centrally, the top of the base member is formed to provide a depression 13 preferably square and adapted to receive a nut 14 which is rigidly secured inthe depression by spot welding or other provision "which willretain the nut in position.-

The floor strip supportingmember 9 is also channel shaped, but its flanges project upwardly so that the member is proportioned to accommodate the nailing ,strip 7 which, when seated in the supporting member, is' 'jsecured therein by nails 15 or other preferred fastening means. The horizontal portion of the upper member is equipped centrally with a downwardly projecting threaded bolt lfi'adapted for threaded engagement with the nut 13 in the base member. The lower end of the bolt is prefer ably enlarged as indicated at '17. so that it can not become unthreaded and accidentally "In the construction of a floor embodying my invention, the floor strip holders are arranged in rows spaced from eachother the requisite spacing of the floor strips, and

- in each row the individual rows are spaced apart a predetermined 'distance' A floor ment of filling holders in is seated in each row of holders and strip1 the olders are'secured thereto by the nails 15. In order to level the floor strips, the base of each holder is rotated upon the bolt 16 until the upper face of the strip is in the requisite horizontal plane with the feet of thebase member upon the rough floor. B I suitably adjusting the individual holders in this manner, the floor stripf can be quickly and accurately adjusted to the proper level and when adjusted, it will be rigidly'supported, by each holder without the-employmaterial such as concrete or the like.

the requislte position, after they have been adjusted they are securely anchored to the rough floor. When the rough floorv is of wooden construction, this is accomplished by nailing the bases of the hold .In a fire proof constructlon embodying a tile, as illustrated in the present drawing, the holders are anchored byfilling' in around thezn' with cement 'or concrete 18 "which, is
